Abstract
  A controlled sol-gel approach was developed to encapsulate luminescent CdTe and magnetic Fe3O4 nanocrystals (NCs) into SiO2 beads. The preparation procedure included the preparation of SiO2-coated Fe3O4 NCs, the attachment of the CdTe NCs on the SiO2-coated Fe3O4 NCs, the assembly of the CdTe NCs-attached ...  Read More
